9. HANDLING BATTERY
Observe the following when handling the battery.
• Before inspecting or handling the battery, be sure to stop the engine, and turn the
starter switch to the “OFF” position.
• Wipe off the dust accumulated on the top of the battery with a moistened cloth.
• The battery produces hydrogen gas, which may
cause an explosion hazard. Do not put fire such as
cigarettes close to the battery or take any actions
that can cause sparks.
• The battery fluid is diluted sulfuric acid, which
corrodes clothes and skin.
Should the battery fluid come into contact with your
clothes or skin, wash the affected area immediately
with plenty of water.
Should it go into your eye, wash your eye
immediately with clean water and consult a
physician.
• Wear goggles and rubber gloves when handling the
battery.
• When removing the battery cable, disconnect the
cable at the ground side (normally (-) terminal) first.
To reinstall, connect it to the (+) terminal first.
Objects such as tools coming between (+) terminal
and the machine body will cause sparks.
• Slackened battery terminals can cause sparks due to
poor contact, causing an explosion hazard. Tighten
securely when installing the terminals.
• Secure the battery when changing it to prevent it from being displaced. If it is not
secured, the terminals will slacken, causing sparks.
• Be sure not to confuse between the (+) terminal and the (-) terminal when removing or
installing the battery cables.
9.1 CAUTIONS IN HANDLING BATTERY
• Always try to keep the battery charged.
The battery should not be charged in a rush after being discharged. Measure the specific
gravity of the battery fluid in advance and charge the battery as needed.
Keeping the battery in the best condition lengthens the life of the battery.
• Check the electrolyte level earlier than regular check and maintenance schedule during the hot
season.
• The battery ability drops significantly during the cold season. Keep the charging rate as close
to as 100 % and try to keep it warm for starting the operation next morning.
Distilled water should be refilled before starting the work next morning to avoid freezing.
